Priority stack
The four things to lock first
Forces, circular motion, and signs/components are the core Test 2 stack. Answer precision is the layer that keeps correct work from being rejected online.
ForcesFree-body diagram -> net force -> acceleration.
Circular motionSome real inward force does the turning job.
Signs + componentsPick axes first; negative is direction, not failure.
Sig figs + notationWhat to type when Canvas wants a number.
Fast rule: name the problem family first, identify the unknown second, list givens third, then pick the equation.

Canvas check
Before submitting a number
Check the equation family, units, sign direction, magnitude, and sig figs. If the value looks right but the online box rejects it, try the plain-number version and the E-notation version.
